Welding machines and joining machines can be supplied as complete systems, which
come with a welding power source, and a weld monitor or controller.
A complete welding machine or joining machine system is comprised of a complete
welding, surfacing, or cutting machine, equipment, or system. Also included are
a power source, torch or gun, cables, feeders, positioners, robots, or other required components.
A power source for a welding machine or a joining machine provides a TIG gun, MIG
gun, electrode holder, laser, electron beam gun or other welding unit with the required
output power to melt material.
Welding monitors or controllers for welding machines are instruments that sense
welding quality (nugget size or weld integrity) or output power supply variations.
Also, welder controllers are used to adjust welding parameters to compensate for
variations in weld quality or output power.
Among the arc or resistance-welding types that apply to welding machines and joining machines are:
- Flux Cored Arc Welding (FCAW)
- Gas Metal Arc Welding (GMAW)
- Orbital / Tube Arc Welding
- Plasma arc welding
- Flash welding
- Projection welding
- Resistance seam welding
- Spot welding
- Shielded Metal Arc Welding (SMAW)
- stud arc welding
- Submerged arc welding (SAW)
- Gas Tungsten Arc Welding (GTAW)
Frictional or other fusion welding types that apply to weld machines and joining machines include:
- Electron beam welding
- friction welding
- Hot plate welding
- plastic welding
- Laser welding
- Oxyfuel welding
- Thermite or exothermic welding
- ultrasonic or linear friction welding
